Advertisement There are tons of holes in this area as well. Only a small majority are actually tarantula burrows. Most of the holes you will see are rodent burrows. It takes seeing a couple to develop an eye for what a tarantula burrow looks like. After awhile it becomes hard to miss them. The easiest ones to find have a thin layer of silk covering the burrow entrance. You will be able to spot the uncovered burrows after you get a feel for what they look like. With more field experience you can spot scorpion burrows, trapdoor spider burrows, and tarantula burrows without breaking a sweat. Okay, this is the desert so you may break a sweat a few months out of the year.
